....data networking capability to mobile hosts. The location aware services enabled by RADAR complement this already useful data networking capability of RF wireless LANs. This makes a wireless LAN more valuable and, in our opinion, increases the chances of large scale deployment. In a previous paper [10], we presented the design of the basic RADAR system and performance results obtained from a limited deployment of the system. Subsequent to that paper, we have expanded the deployment of our system using new wireless networking hardware and a different operating system platform. Over the past year ....
....of the user, has a median of 2 to 3 meters, about the size of a typical office room. Unless otherwise indicated, the experimental results presented in this paper correspond to an empirically constructed Radio Map. A more detailed discussion of the basic RADAR system and its performance appears in [10]. Subsequent to that paper, we have deployed a second RADAR testbed. There are significant differences in the hardware and technology of the two systems. In the next section, we describe both our testbeds, which we used for the experiments reported in this paper. 4 The RADAR Testbeds In this ....

Enhancements to the RADAR User Location and Tracking System - Bahl, Padmanabhan.. (2000) (21 citations) Self-citation (Bahl Padmanabhan) (Correct)
....standardbased [9] RF wireless LAN deployed in our building. Our initial results are encouraging; with a high probability, RADAR is able to locate the user to within a few meters of his or her actual location. In this paper, we analyze shortcomings of the basic RADAR system (discussed in detail in [10]) and develop and evaluate solutions that address these 3 shortcomings. We describe significant new enhancements that we have made. Specifically, we describe a novel access point 1 based environmental profiling scheme that takes into account the reality that RF signals are significantly ....
